As
society's demand for plastic flexible packaging continues to increase, plastic
flexible packaging continues to cover the market with its inherent
characteristics of bright colors, novel patterns, and ease of use. The market
has also put forward higher requirements for plastic flexible packaging, which
not only requires innovative designs to attract more people's attention, but also
requires high barrier properties to maintain the freshness of the contents.
This also requires the shape of the soft bag to be ever-changing, so as soon as
the special-shaped bag came out, it quickly attracted people's attention with
its unique shape and distinctive personality. This article briefly introduces
the production of special-shaped bags and the performance of related equipment
for reference by flexible packaging companies:
1. Types of special-shaped bags
1. The special-shaped bag is sealed on three
sides, and various patterns are directly punched and cut on the three-sided
sealing bag to meet the requirements of daily chemical products, food, etc.,
and reflect the intuitive and vivid characteristics of the product. For
example, various fruit slice packaging bags are designed according to the shape
of the fruit.
2. Self-standing special-shaped bags,
through bottom filling, can make special-shaped bags of various shapes stand
up, fully reflecting the three-dimensional effect of special-shaped bags, and
convenient for display on shelves in supermarkets or shopping malls.
3. Self-standing special-shaped bag with its
own zipper. With the zipper, the bag can be opened repeatedly according to the
unique shape of the special-shaped bag. It is generally suitable for some light
dry goods, such as candies, dried fruits, chocolates, biscuits, jelly, tea,
etc.
4. Use a self-supporting special-shaped bag
with a nozzle for easy dumping of contents. Products with nozzles can be sealed
repeatedly, which means they can be opened and used multiple times. This
special-shaped bag is suitable for liquid beverages, shower gel, shampoo,
ketchup, cooking oil and other liquid products that need to be opened multiple
times.
2. Special-shaped bag manufacturing and
equipment. In some flexible packaging companies, special-shaped bags are formed
by a bag making machine, punched offline with a punching machine, and the
special shape is cut off, and then necessary trimming is performed. This method
wastes a lot of manpower and material resources, and the production efficiency
is not high. At present, the auxiliary equipment of the bag making machine is a
die-cutting machine, which is specially used for the production of
special-shaped bags. Mainly driven by servo motor, equipped with light,
electricity and gas. With the PLC signal, it can be well connected with the bag
making machine to achieve online synchronous die cutting and ensure the bag
making accuracy of special-shaped bags. There is no need for offline subsequent
processing, and it has functions such as online delivery of finished products,
edge trimming, and automatic winding, which greatly improves the efficiency of
making special-shaped bags.
Special-shaped bags break through the
constraints of traditional square bags and change the straight edges of the
bags into curved edges, reflecting different design styles. They are novel,
simple, clear, easy to identify, and highlight the brand image. They also
represent the trend of plastic flexible packaging. Trend direction. At present,
some large domestic flexible packaging companies have been equipped with
corresponding special-shaped bag production equipment. It is believed that with
the development of bag making technology and equipment and the popularization
of die-cutting equipment, the manufacturing of special-shaped bags will no
longer be a problem for flexible packaging companies, and special-shaped bags
will bloom everywhere.
